Application filed January 2,1901. Serial No. 41,922. (No model.)

To all whom, it may concern: a hand-wheel 19, by which it may be rotated Be it known that we, JOHN A. MOSHER and for the purpose of raising and lowering the WILLIAM WISHART, citizens of the United chair. The cell having been seated upon the States, and residents of Chicago, county of chair, the latter is raised, so as to force the 55 Cook, and State of Illinois, haveinvented cerneck 16 of the cell into engagement. wit-h the tain new and useful Improvements in Acetynipple 15. leneGenerators, of which the following is a A ratchet-wheel is fixed upon the screwspecification, and which are illustrated in rod 18, and with it there cooperates a pawl 21, the accompanying drawings, forming part which may be spring-controlled and which IO thereof. prevents the turning back of the screw-rod 18 This invention relates to that type of genin order to disengage the cell from the nipple. erators shown in Patent No. 652,974, granted All of the parts thus far named are shown July 3, 1900, to J.

This is accomplished by interlocking the valves of the cell and piping means of a cam-block 24, shown as being in system and the locking means for securing the form of an inverted truncated cone, which 20 the cell in position; and it consists in the is carried by a rod 25, vertically movable in hereinafter-described construction, which is apertures in the brackets 11 and 12, so that in many respects substantially the same as by the descent of the rod the cam-block forces the construction forming the subject of said back the pawl out of engagement with the Moshers pending application, Serial No. ratchet-wheel, allowing the hand-wheel 19 to 25 27,679, filed August 22, 1900. be turned.

In the accompanying drawings, Figure 1 is At the upper end of the rod 25 there is a a detail side elevation, partly in sect-ion, of cross-bar26,fr0m which there depends a short the generating-cell and the nipple with which rod 27, playing in-a suitable aperture in the it is engaged. Fig. 2 is a detail front elevabracket 12. The valve 23 is provided with a 30 tion of the same. Fig. 3 is a plan of the debackwardly-projecting stem 34, upon which vice as shown in Figs. land 2. Fig. 4is a plan there .is mounted a segmental gear 29, intersection on the line 4 4 of Fig. 1. Fig. 5 is a meshing with a rack-bar 28, fixed to the crossplau section on the line 5 5 of Fig. 2. Fig. 6 bar 26, so that as the valve 23 is turned the is a sectional view on the line 6 6 of Fig. 4, rods 25 and 27 are thereby lowered and raised, 35 and Fig. 7 is a detail of one of the parts of thus etiectingthe engagement and disengagethe device. meut of the cam-block 24 with the pawl 21, so There is shown in the drawings a wall-plate that when-the valve is opened the cam is out 10, to which the generator is secured, being of engagement with the pawl, and the latter carried by brackets 11 and 12. engages the ratchet-wheel 20 to prevent its 4o 13 and 14 are vertical rods connecting the rotation, while the closing of'the valve brings two brackets and serving as guides for the the cam-blockinto engagement withthe pawl, chair 17, upon which the gen eratin g-cell rests. disengaging the latter from the ratchet-wheel 15 is the nipple of the water and gas tubes 20, thus permitting the latter to be turned to (not shown) and is provided with a valve 23. disengage the cell from the nipple 15. 5 5 16 is the generating-cell, having a neck 16, In order to prevent the disengagement of within which there is located a valve 22 and the pawl from the ratchet before the valve 22 which engages the nipple 15. The cell 16 is is closed, a plate 30 is pivoted to the under seated upon the chair 17, having a downside of the bracket 12 and is held by a spring weirdly-projecting stem apertured to receive 31 normally across the aperture within which 50 a screw-rod 18, swiveled in a suit-able hub 11 the rod 27 plays, thereby preventing the dein the bracket 11 and having at its lower end scent of this rod.

An arm 33, fixed to the valve 22, is so disposed as to engage a cam-flange 32, formed upon the plate for the purpose of forcing the plate backwardly against the resistance of the spring 31, so as to permit the descent of the rod 27. It will be seen, therefore, that in order to release the pawl 21 it is necessary first to close the valves 22 and 23 in the order named.

The rod 27 is provided with a notch 27*, adapted to receive the edge of the plate 30 when the latter is released from the arm 33 by the removal of the cell 16, thereby preventing the opening of the valve :33.

By the construction herein shown and described the locking mechanism is materially simplified and its control by the nipple-valve rendered positive. The cell cannot be removed without closing the nipple valve. This valve cannot be closed until the valve in the neck of the cell is closed, nor can it be reopened while the cell is disconnected from the nipple. The opening of the nipple-valve after the cell has been connected positively releases the pawl 21 from its controlling inec hanism, so as to allow it to come into engagement with the ratchet-wheel.

We claim as our invention- 1. In combination, a gas and Water nipple having a valve, a generating-cell having a valve and being adapted to detachably engage the nipple, a detent for locking the cell in engagement with the nipple, means for controlling such detent, and positive connection between such controlling means and the nipple-valve whereby the one is actuated by the other.

2. In combination, a gas and water nipple having a valve, a generating-cell having a valve and being adapted to detachably engage the nipple, a detent for locking the cell in engagement with the nipple, means for controlling such detent, and rack-and-gear connection between such controlling means and the nipple-valve.

3. In an acetylene-generator, in combination, a water and gas nipple having a valve, a generating-cell having a valve and being adapted to engage the nipple, a screw for forcing'the cell into engagement with the nipple, a ratchet-wheel on the screw, a pawl cooperating with the ratchet-wheel, a cam-block for controlling the pawl, a rack-bar for moving the cam-block, and a gear fixed to the nipple-valve for engaging the rack-bar.
